This example shows the basic steps to make the grid editable. To do that we need 3 steps.<br>
1. Mark which column in the grid is editable. This is done with a new property "editable:true"<br>
By default all columns in the grid are not editable.<br>
2. Specify the url where the server accept the posted data. This is done with a option "editurl".<br>
3. Use the three new methods: editRow, saveRow, restoreRow.<br>
- <b>editRow(rowid, keys)</b> - accept two parametres:- rowid - the unique id of the row and keys - which  <br>
when true - we can use Enter and Escape keys to save and cancel editing. <br>
- <b>saveRow( rowid, callback, url, extraparams)</b> <br>
rowid - unique id of the row, callback - custom function - when defined accept data returned from the server after posting, <br>
url - when specified - overwrite the editurl parameter, extraparams - additinal params that can be passed to the server.<br>
When data is posted the format is id=rowid&name=value..., where the name is the "name" from colModel.<br>
- <b>restoreRow( rowid)</b> - restores the data to original values before the editing of the row.<br>
<b>Note:</b> Due to security reasons data is not saved to this server.
